Are the GM Accessory wheels 18x8 or 18x8.5? are they the same as the ones offered on the SRX?
what is the offset and does anyone know the part number?

I put the accessory wheels on my '05. I think they're 8.5, same as stock. Offset seems the same, also. I have two possible part numbers written down, but I don't remember which is correct: 17800209 and 17800210. I paid about $1100 plus shipping for four new ones two years ago from Midwest Wheel on eBay. I hope that helps!

I think the SRX accessory wheels are 20s, though the design looks largely the same.

They are 18x8.5", +42mm offset, just like the stockers. Not sure on part numbers.

What exactly are accessory wheels?
They were the "optional" wheels. 7 twin spokes, polished, 2-3# lighter than the stock wheels. Look like so:

Interestingly, they are significantly cheaper than the stock wheels. I like them better myself, but some don't.

They're also a bit lighter than the stockers.

doesn't matter, knowing OP as I do, he will probably have 4-5 sets of wheels laying around by years end...

I always thought the accessory wheel looked nice, but more like a standard CTS wheel than a V wheel. But when I see them on AAIIIC's car, they really look good. Maybe they just go better with that color.
